IPC: A01K1/015
Filed: 1995-03-20
Abstract: PURPOSE: To obtain a floor material for domestic animals having excellent water-absorption and habitability of the animal and usable as an organic fertilizer as it is because the material forms a compost when mixed with excrement. CONSTITUTION: This floor material for domestic animal is composed of pieces of waste paper having high water absorption and contains rectangular paper strips having a length of 130-1,100mm (preferably 140-820mm) and a width of 3-50mm (preferably 3-40mm) in an amount of >=80%. Preferably the paper is cellulosic waste paper free from plastic films, chemical fibers and synthetic fibers laminated or blended to the paper. Further, the waste paper is preferably selected from newspaper, leaflet, trimmed flush, high brightness, medium one, etc. The problem of deficiency in rice straw caused by the recent structural change of agriculture can be solved by this method.  Since the excrement of domestic animal is treated in the above state, the method is also useful for preventing the environmental pollution and foul smell caused by the contamination of underground water with sewage seeped into the ground.

Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To eliminate the short-circuit fault of a discharging electrode by providing an insulating alumite film on the surface of the electrode, and embedding in micropores formed in the film a metal part in contact with the surface of a material and extended at the end from the surface of the material to the uncrnrty of the film surface. SOLUTION: An alumite film 3 is formed on the surface of a discharging electrode 2 made of aluminum or aluminum alloy wire provided between adjacent cooing fins 12 by anodizing. As a result, many micropores 4 are formed in the film 3. Fine pin-like metal part 5 extended at the end from the surface of a material to the vicinity of the surface of the film 3 is embedded in the micropores 4 in contact with the surface of the material of aluminum or aluminum alloy wire. Accordingly, the metal part 5 is not brought into contact with the heat sink 1 where the part 5 is directly grounded. The part 5 is formed in the many micropores 4, and the part 5 in the micropores has extremely small diameter, and hence even if a low voltage of about 200V is applied, discharge occurs.
